Please don't take this the wrong way, but this seems like an extremely loose and fishy tournament. You have 4 of the first 6 or 7 people at a full table flat calling the BB, and then a small blind making a substandard raise of LESS than 3x the BB, with suited connectors. Then, after you flat call, someone with Q-10 off, a terrible hand, goes all in? And the guy with 10-9 suited calls? This seems very bizarre play to me, extremely loose, and if you knew that this play was atypical of the rest of the tournament, calling with AJs really isn't that bad. However, in a normal tournament setting, I'd have laid this down in a heartbeat. You're too likely to be dominated and don't want to play this hand with 2 others anyway.
